Armin [Ky BUCKLE ATTACHED TO SKI BOOT The invention relates to a buckle attached to ski boots consisting of a toothed tensioning lever pivotally arranged on one instep portion and a longitudinally adjustable clamping loop engageable with the lever and secured to the other instep portion, said clamping loop being so secured by means of a mounting plate and an adjustable plate.

In presently known devices of this type the adjustable plate which carries the clamping loop is secured to the mounting plate by means of a screw or other means. This construction has the disadvantage that a tool must be used for the longitudinal adjustment of the loop and that furthermore a reliable function is not assured.

The basic purpose of the present invention is to produce a simple, safe and strong mounting of the clamping loop which in a simple manner permits a longitudinal adjustment of the clamping loop without the help of a tool. A further purpose is to render the clamping loop pivotable about both a horizontal and a vertical axis.

This purpose is attained according to the invention by providing two or more holes in the one plate, which holes are each connected by a longitudinal slot and are arranged in longitudinal direction of said plate and by further providing a bolt secured to the other plate and fitting into said holes to form a vertical swivel axis. Said bolt is flattened transversely to the longitudinal direction of the plate in such a manner that after the adjustable plate has been rotated 90 said plate can be adjusted longitudinally with respect to the mounting plate, whereby the flattened bolt slides through the longitudinal slot.

The invention will be disclosed more in detail hereinafter in connection with the drawings which illustrate exemplary embodiments.

In the drawings:

FIG. 1 is a diagrammatic view of a clamping loop, adjustable plate and mounting plate;

FIG. 2 is a longitudinal cross-sectional view of the complete buckle secured to the instep portion of the ski boot;

FIG. 3 is a top view of mounting plate, adjustable plate and clamping loop in their normal position;

FIG. 4 is a partially cross-sectional view of this top view after the longitudinal adjustment of the clamping loop;

FIG. 5 is a diagrammatic view of individual parts;

FIG. 6 is a further embodiment.

In the drawing 1 identifies a clamping loop, 2 an adjustable plate and 3 a mounting plate. This mounting plate has holes at the front and rear end thereof which holes according to FIG. 2 serve to secure said mounting plate on the one instep portion 6 by means of rivets 4 and 5. A bearing block 8 is secured to the other instep portion 7. A toothed tensioning lever 10 is supported pivotally about the axis 9 on said bearing block 8. As illustrated in FIG. 2, the clamping loop 1 can engage the tooth spacings of this lever so that by rotating said lever in direction A, the buckle can be tensioned.

Two round holes 11 and 12 are provided in the mounting plate 3 in the illustrated advantageous embodiment. The round holes are connected through a narrow longitudinal slot 13. A bolt 14 is secured to the adjustable plate 2 which overlaps the mounting plate 3, said bolt gripping under the mounting plate with a flat head 15. The bolt has, as can be seen from FIGS. 3 to 5, such a diameter that it fits into the holes l1, l2 and locks, in the illustrated position, the adjustable plate 2 on the mounting plate. This bolt is advantageously flattened on both sides 16, 17 in such a manner that it forms a substantially rectangular cross section and can slide through the longitudinal slot 13 in the position 2 of the adjustable plate 2, which position is illustrated in dash-dotted lines in FIGS. 3 and 4. Thus, for a longitudinal adjustment of the clamping loop 1, it is only necessary to rotate said clamping loop together with the adjustable plate 2 from the normal position (FIG. 3) through 90 into the dash-dotted position 2 and to then move said adjustable plate according to FIG. 4 in direction L whereby the bolt 14 slides through the longitudinal slot 13. The adjustable plate with the clamping loop 1 is then returned through into the normal position illustrated in full lines in FIG. 4.

The above-described embodiment has not only the advantage of the simple longitudinal adjustment of the clamping loop without a tool, but has also the advantage that the clamping loop is not only pivotable in a conventional manner about a horizontal axis a," but furthermore also about a vertical axis b formed by the bolt 14, as is illustrated by the dashdotted swinging positions 1 and 1" in FIG. 4. This free swinging of the clamping loop with the adjustable plate 2 is desired because, during securing of the locking parts, the mounting plate 3 and the tensioning lever 10 often do not correspond in their longitudinal direction.

FIG. 5 illustrates that the flattened bolt 14 has a rivet pin 18 which as shown in FIGS. 1, 2 can be formed into a rivet head. The bolt 14 is thereby supported with the shoulders 20 on the adjustable plate 2. On the one hand, this provides a strong fastening of the bolt 14 on the plate 2, and yet a free movement of said bolt opposite the mounting plate during the longitudinal adjustment is made possible.

If necessary, the bolt 14 can also be connected releasably to the adjustable plate by, for example, constructing the pin 18 as a screw pin and by providing for mounting a nut 21 which can be screwed onto said pin.

In the advantageous embodiment illustrated in FIGS. 1 to 4,

the mounting plate 3 is offset downwardly at both ends at 22 and 23 and also at both sides at 24 so that a hollow space 25 is created between instep portion 6 and mounting plate, in which hollow space the head 15 of the bolt 14 can move freely. Furthermore the end 26 of the mounting plate is advantageously bent to form a U to receive the edge 60 of the instep portion.

The mounting plate and the adjustable plate consist of sheet-metal parts whereby the clamping loop 1 is supported in a conventional manner pivotally about the horizontal axis a on the adjustable plate 2.

FIG. 6 illustrates that, if necessary, three or more round holes 27 can be provided in the mounting plate and can be connected each through longitudinal slots 28 and 29. As a further possibility, the bolt 30 secured to the adjustable plate can be flattened only on one side 31.

The invention is not limited to the illustrated embodiment. Thus, if necessary the round holes and the longitudinal slot can also be arranged in the adjustable plate 2 while the flattened bolt 14 or 30 is secured to the mounting plate.
